IMPROVEMENT lN HAY- LOADERS.

Specification forming part of Letters Patent No. 217,] 10, dated J uly1, 1879; application filed November 9, 1878.

To all whom it may concern: y

Be it'known that I, DEWITT 0. JEWETT, of

. Sand Spring,-in the county of Delaware and State of Iowa, haveinvented certain new and useful Improvements in Hay-Loaders; and I dohereby declare that the following is a full, clear, and exactdescription of the-invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

and yielding rake-teeth, and the incline supported upon springs.

The invention further consists in the construction of the mechanism foroperating the rakes, and in the combination of parts, as will behereinafter more fully set forth, and pointed out in the claims.

In. the annexed drawings, to which reference is made, and which fullyillustrate the invention, Figure 1 is a perspective view of .theimproved hay rake and loader. Fig. 2 is a-longitudinal vertical sectionof the same;

and Fig. 3 shows the construction of the yielding rake=teeth.

B represents the .incline over which the rakes work. This incline is ateach side provided with a frame-work, (l D E, rigidly attached thereto,and substantially .ot' the form shown, or of any other suitable formthat will answer the purpose. Through the lower portions of these framesis passed the axle d, which has its bearings in suitable boxes attachedto said frames. The axle d is provided near each end with a wheel, a,rigidly secured thereon, and upon which the machine is supported.

On the axle d, inside of the wheels e, are

- hung the hounds J J, with the tongue or drawbar K secured to them forconnection with the Wagon. The tongue K is provided with two arms, G G,one extending vertically upward and the other rearward, and these armsare, by springs ff, connected with the under side of the incline B, forsupporting the same in proper position while moving over the field, andat the same time allow it to yield and accommodate itself to anyunevenness in the ground. This is of great importance, as otherwisethe'lower rake-teeth would sometimes not take hold of the hay, and atother times they would be forced into the ground and broken or otherwiseinjured. These difficulties are entirely overcome by the application ofthe springs between the incline and the device that forms the connectionwith the wagon.

Each end of the axle d is formed or provided with a crank, F, which is,by a pitman,

G connected with the lower end of a lever,' O, pivoted to the part 0 ofthe frame. This lever is, ata suitable point above its fulcrum, providedwith a rod, G which connects it with the lower end of another lever, D,pivoted to the part D of the frame.

It will thus be seen that when the machine is in motion these levers Oand D obtain an oscillating movement on their fulcrums, and in oppositedirections.

Over the incline B work two sets or series of rakes, L and L, said rakesbeing arranged alternately, as shown, and connected, respect ivcly, bymeans of cross-bars A and A, so as to form two separate and independentrakeframes. The two levers (3 C are, by rods H H, connected with therake-frame AL, and the two levers D D are, by similar rods I I,connected with the rake-frame A L. The upper cross-bars of the tworake-frames work at their ends in guides K K, parallel to the incline,so as to retain the upper ends of the various rakes in the sameposition, or the same distance from the incline.

The two sets of rakes are moved alternately in opposite directions upand down, while the lower ends of the rakes are at the same time fartherout from and closer into the incline. This is accomplished by thefollowing means: The lower cross-bar of each set of rakes is, at eachend, provided with a friction-roller, z, to move upon a track, B, whichis parallel with the incline. Above this track is a switch, so arrangedthat at the upward movement of the rakes the rollers i will pass underthe same, but at the downward movement the rollers will pass up suchswitches, and thus raise the rakes from the incline, allowing the lowerteeth elevated above and parallel with the track B At the lower end ofthe track B is a pivoted latch, I), held by its own gravity against theend of the track. At the upper end of the track B is a lever, b, pivotedat its lower end, and held by aspring, h, against the end of the track.The upper end of the lever b is made concave, as shown. The operation ofthis switch is as follows: During the upward movement of the rakes therollers i move on the track B, and as the roller strikes the lever 12 itforces the same backward until the roller is caught in the concave endof the lever. The upward movement of the rakes then ceases, and thesprings h, forcing the levers b forwardagainst the tracks B raise therakes to said tracks just as the downward movement ofthe rakescommences. As the rollers i reach the lower ends of the tracks B theypass onto the latches 12 which at once allows the rakes to fall till therollers are on the tracks B the latches at once swinging back andclosing the gap.

The lower end of each rake is provided with a projecting spring-finger,a, to rest upon the ground and aid in preventing any injury to the lowerrake-teeth. This spring-finger is formed with a socket at its inner endto fit over the end of the rake. In the end of the rake under the fingeris a double rake-tooth, m, made of a single piece of wire twisted toform a coil for each tooth, and the center of the wire fastened in therake-bar.

The lower portion of each rake is provided with a series of rigid teeth,12, as this portion of each rake changes its plane of motion, as

I above described, and hence needs no yielding rake, then passed upwardand forward over the rake, crossed and passed through a staple,

s, and the ends turned downward and forward at the sides of the rake andprojecting below the samea suitable distance.

It will readily be seen that these teeth will yield and pass over thehay when moving down, and when movingup they will take hold of and carryup the hay.

In going to and from the field the lower ends of the rakes are raisedfree from contact with the ground by pulling down the upper endof theincline B, and fastening the same by means of a hook, t, or in any othersuitable manner. The platform B is narrowed at the forward end, asshown, so that the hay will fall to the center of the wagon in loading.

Having thus fully described the invention, what is claimed as new, anddesired to be secured by Letters Patent, is-

1. In allay rake and loader, the bed or incline over which the rakeswork, pivoted to an axle and supported on both sides thereof uponsprings, whereby the incline will accommodate itself to the unevennessof the ground, substantially as herein set forth.

2. The combination of two separate alternately-reciprocating sets ofrakes, a mechanism for operating the same, and aset of switches for eachset of rakes, whereby the lower ends of the rakes will be caused to movein different planes during the upward and downward movement,substantially as herein set forth.

3. The combination of the axle (l, with crank F at each end, pitmen Glevers G D, connecting-rods G H I, and the two rake-frames A L and A L,substantially as and for the purposes herein set forth.

4. In combination with a rake-frame, the track B the elevated track Blatch b and concave-ended lever b, with springh, substantially as andfor the purposes herein set forth.

5. The spring-fingers a, secured uponthe ends of the rakes, for thepurposes herein set forth.

6. The double teeth 19, passed through the rake-bar, crossed over thesame through a staple, s, and then bent downward at the sides of thebar, substantially as herein set forth.

7. In a hay rake and loader, the rakes provided at one end with rigidteeth and at the other end with yielding teeth, for the purposes hereinset forth.

In testimony that I claim the foregoing as my ownv I affix my signaturein presence of two witnesses.
